OPEN ACCESS ( OA )
Open access (OA) offers an opportunity to use research outputs (study results and teaching materials distributed online, free of cost or other access barriers.

The OA objective is to autonomise the authors to be independent of publishers and to organise information circulation in the manner which enables researchers to freely disseminate their study outcomes and use the results of research conducted by others so that the expenditure on science can be used effectively. The implementation of Open Science policy in 2019 in Poland led to the initiation of the following programmes funded by Ministry of Science and Higher Education:

1. Open Choice Compact. The licence allows the researchers affiliated in Polish academic institutions to publish OA papers and monographs free of charge under CC BY licence, hybrid journals:
